IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters Patent No. 24,99l, dated August 9,1859.

To all whom it may concern Be it known that I, \VALTER CLARK, ofPalmyra, in the county of Lee and State of Illinois, have invented a newand useful. Improvement in Seed-Planters; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the annexed drawings, forming part of thisspecification, in the several figures ofwhich similar characters ofreference denote the same part.

Figure 1. is a top view of my improved seedplanter. Fig. 2 is a sideview of the same. Fig. 3 is a section on line a: x.

The nature of my invention consists in the arrangement of deviceshereinafter described, which is made up of a series of pins on the wheelof the planter, in combination with a frame having an arm which restsupon the pins on the wheel, and a swinging rod which passes through thedischarge-opening in the seed-hopper, so that by the revolution of thewheel the arm of the frame is raised by the pin on which it rests, and,having passed, it falls 011 the next, thus raising and lowering theframe and constantly keeping the rod in motion through the discharge, soas to pre- 7 vent the seed from clogging in the opening'and the teeth ofthe planter, for the purpose of loosening the earth, making the furrow,and covering over the seed.

The mode of operation is as follows: The revolution of the wheel \V,acting upon the arm of the agitating-frame F, by means of the pins P,keeps the said agitator constantly rising and falling, and the rod 1',passing through the discharge-opening, prevents the seed from cloggingit, the slide 8 regulating the size of the opening. The front row ofteeth, a, break up the ground, the next row, 1), directly in front ofthe discharge-opening, makes the furrow, into which the seed falls fromthe hop per through the opening, and is covered over by the last row, 0.

The great advantage of this construction lies in the agitator passingdirectly through the adjustable seed-opening in the side of the hopper,whereby all danger of clogging is obviated. p

I am aware that the passing of reciprocating rod through thedischarge-tube is not new. Therefore I disclaim this character ofagitator.

\Vhat I do claim, and desire to secure by Letters Patent, is-

The arrangement of the reciprocating agitating-rod 9', when passingthrough the adj ustable seed-discharge opening in the side of thehopper, with the frame F, wheels \V, pins P, teeth a b c, hopper H, andadjustable slide s, the whole being constructed as and for the purposeset forth.

In testimony whereof I have hereunto signed my name before twosubscribing witnesses. \VALTER CLARK. Witnesses: W
